Patient's question:
I take the long-term birth control pill every month on time, but last month I forgot to take it at the scheduled time. I took emergency contraception around December 24th, and until today of this month, my period has not arrived. I have used early pregnancy tests for two consecutive weeks, and all the results have been negative. Today, my husband forgot, and we had intercourse without protection. I don't know if taking emergency contraception again now will be effective. Thank you.Doctor's answer:
The main component of emergency contraception pills is estrogen. These high doses of hormones lead to endometrial hyperplasia, which affects the implantation of the fertilized egg and thus achieves the contraceptive effect. Due to this function of birth control pills, they can cause the menstrual cycle of users to be delayed, which is a normal occurrence. Your situation is preliminarily considered to be the effect of birth control pills. Just wait a bit longer. Emergency contraception pills are only recommended to be taken once or twice a year.
